Cache drive full and going read only with lots of space

[Invincible]

Found the following thread and the output of the commands are posted below:

Running this hasn't seemed to fix anything. 

I'm currently in the process of transferring everything off my cache drive and formatting but would prefer an easier fix if possible.

Done, had to relocate 0 out of 981 chunks

You need to gradually increase the dusage value until at least 75, this thread explains it better:
